Willesden and surrounding areas
In Willesden, commercial premises range from street-level shops and restaurants to offices in converted and modern buildings, many with managing agents and landlord consents to work through.
That includes premises in NW10 and the surrounding districts. Neighbouring towns we cover include Cricklewood, Notting Hill and Shepherds Bush. Buildings across London range from converted period offices to modern units with deep ceiling voids, so we measure each site rather than relying on a standard package.

Things to check in Willesden
Outdoor unit position
Outdoor units need air flow and access, and should be away from neighbours' windows to keep noise down.
Leased premises
If your Willesden premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
Refrigerant rules
Since 1 January 2025, new single split systems holding under 3 kg of refrigerant in Great Britain cannot use refrigerant with a GWP of 750 or more — in practice, R32 or lower.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
Premises we work in around Willesden
- Gyms and leisure: high-capacity cooling and fresh air for gym floors, studios and changing rooms.
- Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.

Compliance in England: refrigerant work falls under GB F-gas rules, and buildings with more than 12 kW of air conditioning in total need a periodic energy inspection (often called TM44).
